Just a quick question . Will this work for the earlier TMP/Spp’s? These didn’t have much of an outer barrel like the MP9 has and “looks” to have a slightly larger diameter. If it’s a yes best believe I’m getting one.

Sorry Ralphie,
Under normal circumstances, you won’t be able to do it.
You would need to source a part from the MP9 for the muzzle to fit.

There was a update between the designs as it moved from TMP to MP9. The base that connected the muzzle to the muzzle base on the TMP was a threaded design, while the updated KWA KMP9 uses two pins to secure the muzzle.

if you can get a hold of Part 15 (Muzzle Base) off of an mp9, you would be in business.

Thank you for replying Dave. Looks like I’m buying an MP9. I’ll leave the TMP original since external upgrades are all discontinued and rare. A new MP9 would be cheaper. KWA wouldn’t sell me the MP9 upper receiver so I can have at least a top rail for the tmp, sucks. Take care!
